How the formula works
Both nanojoule and picojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1000 to get picojoules. To reverse the conversion, multiply a picojoule value by 0.001 to get back to nanojoules.
Frequently asked questions
What is Nanojoule (nJ)?
A nanojoule (nJ) is a metric-prefixed unit of energy equal to 10-9 joules, a fraction of a single joule, using the SI nano prefix.
What is Picojoule (pJ)?
A picojoule (pJ) is a metric-prefixed unit of energy equal to 10-12 joules, a fraction of a single joule, using the SI pico prefix.
How do I convert nanojoules to picojoules?
Multiply the nanojoule value by 1000 to get the equivalent in picojoules. For example, 5 nJ × 1000 = 5000 pJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1000 is an exact, non-rounded value.
Can I convert picojoules back to nanojoules?
Yes. Divide the picojoule value by 1000, or multiply it by 0.001, to get nanojoules.
